Rear Air Ride Random Drops / Air Blending Door

[myrddin]

I understand... I just don’t get how the software can let the rear drop over time like that... Seems like I could hear it or something...

Currently at: This is as of 8:25pm...
Passenger 40 3/4 best I can tell
Driver 41 1/2 (-2 mm)


So let’s look at it like this, its dropping, so air is coming out of something... Is there an exhaust valve that has a vent for the air? Would it be dumb to try to put a balloon over it to see it shows signs or air escaping?

What if it’s a leak somewhere I can’t see to spray?

Man, it’s bad enough when you need to work on something but usually you know what it is.


The air is currently working, it was just the one time... but like you stated... could be sign of what is to come.

If you guys say its worth my time then I will do it... I just wish I had more signs to point my finger at is all.

I did find this and I am not real sure what it means (like what had to be fixed) but:
